In the next couple of months I am giving a presentation at a SolidWorks User Group Meeting, and I am not sure what topic I would like to focus on. I have about a half an hour to give said presentation, and would like to do something basic that someone who just knows the basics could learn, do hands on with me, and also find interesting. If anyone has any ideas feel free to let me know. No idea is a bad idea.

If you're talking about very new users. In addition to the points suggested already, I would talk about the benefits of using sketch relations vs. using dimensions and how they affect file size and rebuild times in complex models.

Then talk about design intent:

How do you want the final part oriented? If it's symmetrical, do you want one of the standard planes to act as a plane of symmetry? Do you want to model half and then mirror it at the end? Think of where the planes will end up in the final part and how someone would use them to mate this in an assembly.

If you can put all of the cut-extrudes in one feature, should you? How does this affect future modification? Is it easy for others to know what you have done when they need to make the change?

When should draft and fillets be added? (this is a bit more advanced but it's best to add them as late as possible in the feature tree)

2. Creating a single camera and then controlling the camera actions in Animation timeline. (I can do it - but it always seems that I am doing way to much work for something that is simple in my other CAD).

(User Groups are going to be pretty savvy, so you could do some advanced techniques.)

If you wanted to have some fun with the very basics, you could think about showing some techniques to be efficient when creating sketches.

Create a sketch that is "semi-complex" (being sloppy here is good for demonstration purposes.)

Use "Auto dimension" to fully define the sketch (this should make a huge mess of dimensions.)

Ask them if this demonstrates good "design intent" and if it would be easy to make changes.

Do a screen grab to refer back to later.

Use a filter and delete all dimensions (you could use "show relations", but we'll make it easy and keep the relations from the sketch.)

Now go through and add relations

Finish with well thought out dimensions to fully define the sketch

Show the difference in the two sketches.

A lot of people don't realize that you can have a robust, fully defined sketch with only a few dimensions if you put some thought into your relations, use Global Variables, use equations, link dimensions, and so on.

Even some of the "more seasoned" users can get some good information out of something like this.
